- Letters Patent No. 90,145, dated May 18, 1869.

; IMPROVEMENT IN CARRIAGE-SPRINGS.

The Schedule i'eferred to in'these Letters Patent and making part of the name.

To all whom it may concern; 7 v

Be it known that I, ALLYN E. 'Woncorr, of Chicago,

in the county of Cook, and State of Illinois, hai'e invented anew and useful Improvement in Metallic Springs; and l doherebydeclare the following to be a full, clear, and exact description of the same, reference being had to theaecompanying drawings, and the letters and figures marked thereon, which form a part of this specification, and in which- Figure 1 represents aside elevation of my improved spring, and

Figure 2, a top or plan view; The natureof my invention consists in the combination of a suspended coiniecting-pieee, adjusting-links,

metallic springs, and curved bearings."

To enable those skilled in the art to understand how to manufitcture and use my invention, I will proceed to describe the same with particularity; 1

. The same letters of reference refer to the corre- 1 spending parts in the different figures.

.In the annexed drawings-- A A represent two straight metallic resilient plates U or springs, and

B, cnrved bearings for the springs to rest upon as f they are sprnng'down by the weight.

The springs and these I bearings are fully described in my application for a patentibraii improvement in metallic springs, of even date herewith.

From the ends'of the springs A are suspended the ad j nstin g-links O, the lower ends of which are connected by the connecting-beam D.

This form of my improved spring is a change in its application to adapt it to suspended weights, or where it is desirable to have theweights ,below the curve bearingsof the springs, as in locomotives.

One or more springs, E, may be placed beneath the principal springs A, to strengthen them. i

The lengths of the adj usting-links G are intended to be such that when the endsof the springs A, to which they are suspended, strike the curved bearings, they will form a tangent to the circle of the bearings B.

' The linesH indicate the base of the curved hearing, which may be supported in any suitable manner.

Having fully described the construction and operation of my invention,

' What'l claim, and desire to secure by Letters Patent, isg V i V ,l. The combination of the curved bearings B, springs A, suspended adjusting-links O, and connecting-bar D,

whemeoiistructed and arranged so as to operate substantially as andfor the purposes set forth.

2. The combination of the springs A A and the curved bearings B B, arranged to operate substantially as herein set forth, either with or without the suspended links 0 O and connecting-bar D, or either of them.
